Question 14: Select all correct statements which applies to seed nodes

1. Use the multiple list of seed nodes in a cluster, so all nodes quickly learn about all other nodes in the cluster
2. The seed node designation has no purpose other than bootstrapping the gossip process for new nodes joining the cluster
3. Seed nodes are not a single point of failure
4. Seed nodes are a single point of failure

1. A, B
2. B, C
3. C, D
4. A, D
5. B, D

Correct Answer: 2

Explanation: To prevent problems in gossip communications, use the same list of seed nodes for all nodes in a cluster. This is most critical the first time a node starts up. By default, a node remembers other nodes it has gossiped with between subsequent restarts.

The seed node designation has no purpose other than bootstrapping the gossip process for new nodes joining the cluster. Seed nodes are not a single point of failure, nor do they have any other special purpose in cluster operations beyond the bootstrapping of nodes.
